Question

Find two integers whose sum is -3 and product is -18

Answer 1

let two integers be x and y

A.T.Q

x+y= -3

or, x= -3-y(i)

and xy= -18

or,(-3-y)y= -18[by(i)]

or,- -3y-y²= -18

or,-y²= -18+3

or, -y²= -15

or, y²=15

therefore y=✓15

from (i)

x= -3-✓15

y=√15

Answer 2

Answer:

3 and -6

Step-by-step explanation:

1. First, let's find the factors of -18

• -1 and 18, or -18 and 1
• -2 and 9, or -9 and 2
• -3 and 6, or -6 and 3

2. Next, we have to find which of the factors add up to -3.

• $-1 + 18 = 17$
• $-18+1=-17$
• $-2+9=7$
• $-9+2=-7$
• $-3+6=3$
• $-6+3=-3$

3. Great! Now that we found the factors that result in a product of -18 and a sum of -3, the factors are 3 and -6.
